Answer:
A bicycle locked to a bike
Explanation:
The kinetic energy of an object when an object is moving. The mathematical expression for the kinetic energy of an object is given by :
Where
m is the mass of an object
v is the velocity of an object
First option : A car driving down a road, the car is moving i.e. it will possess kinetic energy.
Second option : A soccer ball rolling down a hill, the ball is moving i.e. it will possess kinetic energy
Third option : A bicycle locked to a bike, neither bicycle nor bike is moving i.e. it will not possess kinetic energy.
Fourth option : A satellite orbiting Earth, the satellite is moving i.e. it will possess kinetic energy.
Hence, "a bicycle locked to a bike " has least amount of kinetic energy.
